Any ideas? 6 DPO

I have had 1 day of brown/pink discharge/spotting only when wiping and not every time. It’s more than just a few dots of blood but nowhere near the severity of a period. With light cramps. Cramps have continued but no spotting today. Cramps are similar to the beginning of AF - not severe just uncomfortable. Any idea what this might be? Could it just be a very early period? Rest of discharge is clear but creamy consistency.
